Nice set Phil, I was looking at the exif on #2 as all your shots are crisp and sharp. I tried identical setting on my D40X with a 18-200 @24mm, aperture priority @F4, ISO 200. The speed calculated by the camera was 1/1000 which is less than half of your speed of 1/2500. The conditions were similar, bright blue sunny sky, even facing close to the sun I could not attain that speed on aperture priority, removing the UV filter only gave me 1/1250. Looks like the technology changed drastically from the D40X to the D90. I’m looking to make sharper images as I think mine lack this.
